Ensamble FenixEnsamble Fenix hails from Venezuela where they have become national icons after hundreds of performances and their 2012 hit release, "Guayoyo". From the World Festival of Choirs in Puebla, Mexico to International Culture Week in Colombia, to concert tours of Madrid and Barcelona with the Venezuelan Embassy, this jazzy sextet has amazed audiences with their rhythmically intricate, harmonically romantic, latin style.

[ATTENTION: Ensamble Fenix was originally scheduled to perform ON Sat 7:00PM and Sun at 2PM, HOWEVER, as of March 31st, the government of Venezuela has altered its position on allowing the members of the group to travel freely. We will do everything in our power to assist our friends in Ensamble Fenix, but the wheels of governments everywhere turn slowly, and we are unsure whether they will be permitted to join us here in the United States. If they can make it, we will welcome them. If not, our hearts are with them.]

Their specially tailored school show has been hailed “brilliantly entertaining and educational” and "the perfect school assembly” by countless teachers and administrators. In 2010, original members Paul Iams (tenor), Chris Brown (baritone) and Mark MacLean (bass) welcomed veteran tenor David Wilner (Blind Man’s Bluff, Fiveplay) into the group. In 2012, Ac•Rock celebrated their 20th anniversary with the release of “Framed!”, the group's seventh studio album. Keep an eye out for Ac•Rock’s eighth album in early 2015. [Performing Sat 9:30PM]

Grace McLeanHuff Post calls this NYC-based live-looper, "Electrifying!" Manhattan User's Guide writes, "This pop and jazz singer writes seriously infectious melodies with seriously antic lyrics. Her voice can raise the roof, or she can slide off a note and break your heart." Sometimes compared to artists like Kimbra and Julia Easterlin, once McLean begins, you won't be able to take your eyes off her for a moment. She loops layer upon layer of live harmony over her live leads, all the while putting the audience's focus on her incredible singing and songwriting. It's only after, that one marvels at her mastery of the technology. McLean made her mark in theatre and indie rock. SingStrong marks McLean's a cappella festival debut.
